FR4 is the backbone material upon which most rigid circuit boards are built. However, many are unaware of what FR4 is, let alone why it is the most popular PCB base A printed circuit board can have multiple copper layers. A two-layer board has copper on both sides; multi layer boards sandwich additional copper layers between layers of insulating material. Conductors on different layers are connected with vias, which are copper-plated holes that function as electrical tunnels through the insulating substrate

Epoxy resins have good mechanical and electrical characteristics, which is why they're the most commonly used material in making printed circuit boards. Aside from having great features, epoxy resins are also inexpensive, and dissolves quickly and safely in cheap solvents, making them easy to use My question is about how to substantiate flammability for FR-4 Printed Circuit Board material. I used to just say that it was UL 94-V0 rated. But I have heard rumors that the 94-V0 rating is no longer sufficient. Is that true, and if so how do I substantiate the flammability of FR-4 short of burning it. Repl
FR-4 is a common material for printed circuit boards (PCBs). A thin layer of copper foil is typically laminated to one or both sides of an FR-4 glass epoxy panel. These are commonly referred to as copper clad laminates. The copper thickness or copper weight can vary and so is specified separately The expansion is expressed in parts per million per degree Celsius (ppm/°C). A PCB will expand in length or width by 14 parts per million per Celsius degree. This means that if a PCB were 1 million inches long, it would expand by 14 inches for every Celsius degree of temperature increase. A typical FR-4 laminate has a CTE of 14 to 17 ppm/°C
Standard FR4 boards have a Tg of 135C to 180C while Rogers 4350B and 4003C has a Tg >= 280C. Shown above, the Rogers materials have much less signal loss due to the PCB materials absorbing the signal vs. FR4. This is also called PCB material loss. At about 6 to 7 GHz the signal loss is typically about 0.5 dB more in FR4 but this is design and. .

What is PCB? PCB is a copper laminated and non-conductive Printed Circuit Board, in which all electrical and electronic components are connected together in one common board with physical support for all components with base of board.When PCB is not developed, at that time all components are connected with a wire which increases complexity and decreases reliability of the circuit, by this way. High-Performance RF PCB Materials. The next step up in improving on FR-4 is to use a high-performance material like the mentioned Rogers RO4350B  and others. As can be seen in figure 2, the RO4350B PCB loss is less than half the loss of FR-4 at 6 GHz. While this may not be too important and not worth the extra cost if your circuit operates.
